IGMP/MLD IP Multicast Group
The IGMP/MLD IP Multicast Group Page displays the IPv4 and IPv6 group address
the switch learned from the IGMP/MLD messages it snoops.
There might be a difference between information on this page and, for example,
information displayed in the
MAC Group Address Page. Assuming that the system
is in MAC-based groups and a port that requested to join the following Multicast
groups 224.1.1.1 and 225.1.1.1, both are mapped to the same MAC Multicast
address 01:00:5e:01:01:01. In this case, there is a single entry in the MAC Multicast
page, but two entries on this page.
